Engineers Filter is a filter plugin that allows for extremely steep filtering.

It achieves this by implementing high order IIR filter design methods that are commonly used in science and engineering, namely Butterworth, Chebychev, inverse Chebychev and elliptic (aka Cauer) filters.Each of these filter design methods can be applied to create:

RS-MET has recently released a VST/AU called ToolChain. It is 64-bit, free and acts as a bundle/shell for several effects created by the developer, including Engineers Filter. You can download from developer's website.

Excellent steep filter! To control/automate parameters in FL Studio, you can use 'MIDI Out' to send MIDI CC messages. In more detail: 1.) In the FL Studio Wrapper of EngineersFilter (EF): Set a MIDI input port (e.g. 10). 2.) In the FL Studio Channel Rack: Create a MIDI Out channel and match the Port number to the one previously selected (here: 10). 3.) In the MIDI Out: Right-click one of the round knobs and choose 'Configure' in the drop-down menu. Fill in name and short name, and set the CC number in the 'Controller' field to an unassigned number (e.g. CC 23), then click 'Accept'. 4.) In EF, right-click on the parameter you would like to control via MIDI CC (e.g. Frequency) and choose 'MIDI Learn' from the drop-down menu. 5.) Immediately thereafter, switch to the MIDI Out and use your mouse to move the round knob you assigned in Step 3 (here: MIDI CC 23). This will automatically link this knob to the chosen parameter in EF, i.e. moving the round knob in MIDI Out will now change the assigned value in EF. 6.) Repeat procedure for other parameters, using different MIDI CC numbers. 7.) Optional: After right-clicking once more on a round knob in MIDI Out, link it to your hardware controller or assign an automation clip as described elsewhere.

I'm so confused. I extract all of the files to my plugin folder in Ableton and nothing is showing up! I've tried closing out of Ableton and loading it back up and still nothing. Can someone please help me?

This is a "32 bit- plugin" . Maybe you own a relative new 64 bit- ableton- version. Then you'll need a 64 bit converter like "j- brige" for this plugin (and all the other fine 32 bit- plugins around the world). Hope that helps...

This is an awesome filter. Excellent for experimental sound design, and the customization is really nice. Also freaked me out a bit when I noticed my last name is one of the filter modes (Butterworth). My only problem with it is that I couldn't seem to find any way to MIDI map/automate the controls in FL Studio. Anyone got any suggestions?

Damn, this is super useful for mixing. Want more headroom? Try high passing things with this. The only way you'd tell it was free was just by the way you dial up the numbers. Other than that, really quality stuff.
